Help with driver

I have a chilledtech 660w kit that I have put together. I have gotten it completely assembled but I haven't hooked the driver up yet. There is 2 outputs off the driver and I'm not 100% sure which one I'm supposed to use. Any help would be appreciated so I dont screw things up lol

Did the kit come with instructions?

That's all I got lol one of the outputs has a cap on it so I'm pretty sure it's the one without the cap but just want to make sure
